    type:         quadword integer (signed)
    access:       read only

    2     Number of successful calls to LIB$FREE_VM_64
    3     Number of bytes allocated by LIB$GET_VM_64 but not yet
          deallocated by LIB$FREE_VM_64

    6     Number of calls to LIB$FREE_VM_PAGE_64
    7     Number of Alpha pagelets allocated by LIB$GET_VM_PAGE_64
          but not yet deallocated by LIB$FREE_VM_PAGE_64

    Note that it is invalid to omit code or to give a code of 0 or 4.
